The ultimate virtual dice experience for games and decisions 🎲
A dice roller is a free online tool that simulates rolling physical dice, generating random numbers for games, decisions, educational purposes, and entertainment. Whether you're playing Dungeons & Dragons, teaching probability to students, making random selections, or playing board games without physical dice, our virtual dice roller provides instant, fair, and truly random results for any dice type—from standard six-sided dice to specialized gaming dice like d4, d8, d10, d12, d20, and d100.

No need to carry physical dice. Roll anytime, anywhere from your phone, tablet, or computer.
Computer-generated random numbers ensure truly unbiased results with no physical imperfections or rolling technique bias.
Never worry about losing dice or having incomplete sets. All dice types are always available.
Roll dice without disturbing others—perfect for late-night gaming sessions or quiet environments.
Roll multiple dice instantly without the time needed to physically roll and count numerous dice.
Teach probability, statistics, and mathematics with instant visual feedback and roll history.
Many virtual rollers track roll history, useful for verifying results or analyzing probability patterns.
Access rare or expensive dice (d100, d30, etc.) without purchasing physical copies.
Yes, our dice roller uses cryptographically secure random number generators that produce statistically random results. Each roll is independent, meaning previous rolls don't affect future outcomes—just like physical dice.
Absolutely! You can roll anywhere from 1 to 100+ dice simultaneously. This is especially useful for games requiring multiple dice rolls or calculating large amounts of damage.
A "natural 20" (or nat 20) means rolling a 20 on a d20 without any modifiers—the highest possible result. In D&D and similar games, this is usually an automatic critical success. Similarly, "nat 1" is an automatic critical failure.
Roll two d10s—one represents tens (00-90) and one represents ones (0-9). Combine them: rolling 70 and 3 = 73%. Rolling 00 and 0 = 100%. This simulates a d100.
While our dice roller provides fair random results, we don't encourage or support gambling. Use it for entertainment, games, and educational purposes only.
Virtual dice are convenient when you don't have physical dice available, need to roll many dice quickly, want guaranteed randomness, need specialty dice, or prefer silent rolling that doesn't disturb others.
d20 is the primary die in Dungeons & Dragons (all editions), Pathfinder, d20 Modern, and many other tabletop RPG systems. It's used for ability checks, attack rolls, and saving throws.
The standard method is "4d6 drop lowest" rolled six times (once for each ability). Our roller can do this, or use alternative methods like "3d6" (average results) or "2d6+6" (heroic characters).
Many virtual dice rollers include roll history features that let you review recent rolls. This is useful for verifying results, tracking patterns, or recording important game moments.
For a single d6: each number (1-6) has 16.67% chance. For 2d6: 7 is most likely (16.67%), while 2 and 12 are least likely (2.78% each). Probability changes with number of dice and sides.
Modifiers are applied after rolling and summing all dice. For example, "3d6+4" means roll three six-sided dice, sum them, then add 4 to the total.
Yes! Many dice rollers allow custom dice with any number of sides, perfect for unique game mechanics or special applications. You can create anything from a d3 to a d1000.
In D&D 5e, advantage means rolling 2d20 and taking the higher result. Disadvantage means rolling 2d20 and taking the lower result. This significantly changes success probability without adding math.
Depends on your weapon and level. Starting weapons might be 1d6 or 1d8. Higher-level attacks could be 3d8+5 or more. Spells like Fireball use 8d6, requiring multiple dice rolls.
Absolutely! Monopoly uses 2d6 (two six-sided dice). Virtual dice work perfectly for all traditional board games that require dice rolling.
d6: Each number has 16.67% chance (1 in 6)
d20: Each number has 5% chance (1 in 20)
d100: Each number has 1% chance (1 in 100)
Rolling multiple dice creates a bell curve rather than flat probability:
2d6 Results (Monopoly, Craps):
3d6 Results (Classic D&D Stats):
Both have their place! Many gamers use virtual dice for convenience and speed while keeping physical dice for important rolls and atmosphere.
